arr: fix prowlarrUrl for cross-netns reachability
All checks were successful
Build and Deploy / deploy (push) Successful in 1m47s

Browse Source 
Prowlarr runs in the wg VPN namespace; Sonarr/Radarr run in the host
namespace. Configuring the Prowlarr sync with prowlarrUrl=localhost:9696
made Sonarr/Radarr try to connect to their own localhost, where
Prowlarr does not exist — the host netns. Every indexer sync emitted
'Prowlarr URL is invalid' with Connection refused (localhost:9696).

Use vpnNamespaces.wg.namespaceAddress (192.168.15.1) so host-netns
clients hit the wg-side veth where Prowlarr is listening.

Also re-enables healthChecks on prowlarr-init: the /applications/testall
endpoint now validates clean (manually verified via API).
